Back

ATP

Front

What are cilia and flagella used for in organisms?

Back

Movement

Front

What happens to a freshwater plant's cells when placed in saltwater?

Back

They will shrink because water moves out.

Front

What indicates that a cell is using active transport?

Back

ATP is being rapidly consumed near the cellular membrane.

Front

Define active transport in cells.

Back

The movement of substances against their concentration gradient, requiring energy (ATP).

Front

What is the role of the cell membrane?

Back

To regulate what enters and exits the cell, maintaining homeostasis.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport does.

Front

What is a contractile vacuole?

Back

An organelle that helps eliminate excess water in certain protists.
